Import 6es7323-1bl00-0aa0 — Buy in wholesale FOB from Supplier in China

The 6ES7323-1BL00-0AA0 is a Siemens SIMATIC S7-300 SM 323 digital input/output module, combining 16 digital inputs and 16 digital outputs in a single-width S7-300 slot. Unlike discrete input-only or output-only modules, the SM 323 integrates mixed-signal capability for compact machine control architectures where I/O density and cabinet space are constrained. The module interfaces to the S7-300 backplane and requires a 20-pin front connector for field wiring; output channels are typically transistor-based with short-circuit protection, though the exact switching characteristic and load current rating must be confirmed against the Siemens product data for this MLFB.

Construction follows the standard S7-300 modular format with a robust housing for DIN-rail mounting in industrial control panels. Input channels accept 24V DC signals with internal optical isolation, while output channels source 24V DC to loads such as solenoid valves, contactor coils, and indicator lamps. SM 323 modules in the 6ES7323-1BL00-0AA0 configuration typically support output current ratings of 0.5A per channel with collective current limits per module, though these figures should be treated as typical for the product family and verified for the specific unit. The 20-pin front connector permits dense wiring; spring-clamp or screw variants are standard Siemens accessories ordered separately.

This combined I/O module suits OEM machine builders, system integrators, and MRO professionals expanding or refurbishing S7-300 installations in discrete manufacturing, packaging machinery, and material handling. Moore Plc Limited, based in Xiamen, Fujian, positions itself within a broader automation spare parts trading operation with decade-plus market presence. Buyers should treat the 6ES7323-1BL00-0AA0 as a specific catalogue item requiring exact MLFB match for functional equivalence, and confirm with Moore Plc Limited whether the offered unit is new, refurbished, or surplus, along with any accompanying Siemens documentation.

Moore Plc Limited is located in Xiamen, Fujian Province, China, with postal code 361009. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and zero recorded average response hours. The company profile indicates more than a decade of activity in industrial automation spare parts supply, serving global demand for obsolete and current automation components from manufacturers including Siemens, Allen-Bradley, ABB, Bently Nevada, Schneider, General Electric, Westinghouse, Invensys Triconex, and Honeywell.

The listing does not state whether Moore Plc Limited is an authorised distributor for Siemens or any other brand, nor does it disclose inventory ownership, warehouse location, refurbishment capability, in-house testing infrastructure, or quality certification. No employee count, annual revenue, or named client references appear in the available profile. The extensive product list spanning multiple PLC and DCS platforms suggests a trading model focused on sourcing and brokering rather than manufacturing. Buyers should independently verify authorisation status and request evidence of stock holding for the specific 6ES7323-1BL00-0AA0 before committing funds.
